FAQ — Terex jaw crusher parts

Are Terex JW and JS jaw plates interchangeable?

No. JW series (JW42, JW55) uses a different bolt pattern and plate design than JS series (JS3750, JS4552). Always confirm your exact model — JW plates will not fit JS machines and vice versa.

How can I extend jaw plate life on my Terex crusher?

1) Maintain correct CSS — undersized CSS concentrates wear on the plate bottom. 2) Feed into the chamber center — side loading causes uneven wear. 3) Replace cheek plates when deeply grooved — worn cheek plates allow material to bypass the jaw plates and erode the frame.

What is the hydraulic wedge adjustment system?

Terex JW series uses hydraulically actuated wedges instead of manual shims. CSS changes take under 5 minutes — no jacking bolts, no shim packs. This is a key advantage over manual-shim jaw crushers when you need to adjust CSS frequently for different products.
